Chip-Level Channel Equalization in WCDMA Downlink
EURASIP Journal on Advances in Signal Processing, 2002 The most important third generation (3G) cellular communications standard is based on wideband CDMA (WCDMA). Receivers based on TDMA style channel equalization at the chip level have been proposed for a WCDMA downlink employing long spreading sequences ...

Advanced Science, EarlyView.A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Optical and electrical equalizers for fiber optic links
, 2017 Optical equalizers and electrical equalizers for a fiber link has been explicitly studied and compared. The results demonstrate that both can improve optical links significantly but optical equalizers can perform better in terms of noise ...

Robust Design of Adaptive Equalizers
, 2012 Although equalizers promise to improve the signalto- noise energy ratio, zero forcing equalizers are derived classically in a deterministic setting minimizing intersymbol interference, while minimum mean square error (MMSE) equalizer solutions are ...

Advanced Science, EarlyView.As engineered nanomaterials gain prominence in cancer imaging and therapy, understanding their impact on tumor progression becomes increasingly critical. We demonstrate that gold and silica‐coated gold nanomaterials can either suppress or enhance breast cancer metastasis through distinct tumor microenvironment interactions, while identifying ...

Performance comparison among neural decision feedback equalizers
, 2000 Neural networks add flexibility to the design of equalizers for digital communications. In this work novel decisionfeedback (DF) neural equalizers (DFNE) are introduced and compared with classical DF equalizers and Viterbi demodulators.

A Unified Framework for Group Delay Flattening: Stable and Hardware-Efficient All-Pass Networks
IEEE AccessThis paper presents a unified framework for group delay (GD) equalization and phase distortion compensation using cascaded all-pass filter (APF) networks. The proposed approach addresses the critical limitation of finite impulse response (FIR) equalizers,

Equal Opportunity, Equality, And Responsibility
, 2007 This thesis argues that a particular version of equal opportunity for welfare is the best way of meeting the joint demands of three liberal egalitarian ideals: distributional equality, responsibility, and respect for individuals’ differing reasonable judgements of their own good.
